Prevalence of Candida albicans in patients receiving total parenteral nutrition.

The prevalence of Candida albicans was quantitatively compared in 74 surgical patients during and after total parenteral nutrition (TPN). Suppression of oral food intake is probably responsible for the decrease of the C. albicans population in the mouth.

Systemic opportunistic fungal infections.

The clinical manifestations of "opportunistic" fungal infections in compromised hosts, asthenomycoses, differ from those caused by the same fungus in otherwise normal people. Examples are given on the field of dermatophytoses, aspergillosis, candidiasis and cryptococcosis.

[Opportunism in dermatophytes].

Dematophytes invade hosts when their state is suitable for the production of their pathogenicity. When the host's resistance is reduced, the prevalence of dermatophytoses can be extremely high or the symptomatology can be very unusual. It is suspected that the 'maladie dermatophytique' and pherhaps dermatophytic mycetoma develop in such situations.

[Reflections on dermatophytes].

In light of his experiences especially in tropical regions, the author makes some remarks about dermatophytes and dermatophytia, which they cause. The following main items are: 1. The dermatophytes lead a saprophytic life.

[Moder classification of dermatophytes].

Dermatophytes are classified according to two systems. The first, or parasitic classifications of Sabouraud, rests on the morphology of the dermatophytes on the hair in vivo (Achorion, Trichophyton endothrix or ectothrix microides and megaspores, Microsporum) or on the absence of growth on the hair in vivo (Epidermophyton). In the second type they are classified according to their saprophytic morphology.

Therapy for deep mycoses: an introduction.

A classification of mycoses, depending upon the depth of penetration of the organism is discussed, as is the need to distinguish the true from the 'pseudo' mycoses. The development of antifungal agents is described from the first antibiotics to amphotericin B and 5-fluorocytosine. Attention is particularly focussed on the question of safety and effectiveness.

[Rhinosporidiosis: clinical aspects, epidemiology and ultrastructural studies on Rhinosporidium seeberi].

The author revises the main clinical aspect of the disease as well as its dignosis and its treatment. Rhinosporidium seeberi, first described by J.R.
